III 1-2 Ionic Bonding + Structure valance electrons: elections in the outermost energy level -Valance electrons are responsible for atom characteristics. "most atoms want a full set of valance electrons (8 is great)) • Atoms in the same group have the same outer electronic structure and the same number of valance electrons Lewis Diagrams: -Shows the valance electrons of an element Ex: .N. -nitrogen symbol goes in the middle -dots show the 5 valance elections. . 1 The Octet Rule: in forming compounds, atoms tend to achieve a noble gas structure; 8 in the outer lever is stable. Bonds happen so elements can have full valance Shells The jonic substance is held together by strong electrostatic attractions in all 3 dimensions. • Ionic compounds form by an atom transfering. electrons to fill another atoms Valance shell • Many transition metals have more than I possible. loxidation state and in written form that means you must use roman numerals to show the charge Ex: Iron (11) = Fe ¹² Trick for writing lonic compound formulas: • Cross and drop!!
